No, girls cannot have boy private parts. The biological sex of a person is determined by their chromosomes and their reproductive organs. Girls are typically born with XX chromosomes and have a uterus, ovaries, and a vagina.
While there are cases of individuals born with atypical genitalia or intersex variations, this does not change the fact that girls are biologically distinct from boys. People who are intersex have genitals, chromosomes or reproductive organs that don't fit into a male/female sex binary. Their genitals might not match their reproductive organs, or they may have traits of both. Being intersex may be evident at birth, childhood, later in adulthood or never.
It's important to respect and understand the diversity of human bodies and avoid making assumptions about someone's sex or gender based on their appearance.
